Thanks for this interesting link! After landing here a couple of days ago, just want to say thank you also for sprinkling diverse tidbits of interest all around the site :)

In this study, the two groups seem to differ on many factors other than language type, so I thought the authors' attribution of connectivity differences to characteristics of the two of the languages was not as well supported as one might like. But it is an interesting idea!

This is super cool, I wonder what the widest variance in languages would be, like German -> Arabic, Chinese -> !kung
